Description

External bracket and gravity type structure Technical Field The utility model belongs to the technical field of wharfs, and particularly relates to an external bracket and a gravity type structure. Background The gravity type wharf structure is widely applied to the field of wharf engineering as a common wharf structure type, has the characteristics of high rigidity, high load adaptability and high durability, and has certain applicability, and is suitable for geological regulation, large prefabricated fields, continuous wharfs and open sea pier wharfs. The caisson is a common gravity type structure, and is a large reinforced concrete compartment empty box. The box outer structure mainly comprises concrete bottom plate, outer wall, and the incasement is divided into a plurality of bin check by horizontal, longitudinal partition wall, adopts packing such as block stone, well coarse sand to backfill to the top surface in the caisson bin check generally, but sometimes the pier is located in non-rock foundation, in order to reduce the consideration in the aspect of pier foundation bed bottom stress as far as possible, the bin check backfill of pier front edge is not full in partial structural design, so forms the empty bin between upper portion breast wall structure and backfill, needs to design independent bin check apron as the die block to support upper portion breast wall structure construction this moment. The grid cover plate supporting structure can adopt reinforced concrete brackets or pre-buried steel members. However, the inner formworks of the prefabricated caisson structure are mostly integrally combined inner containers, the installation and the detachment of the inner formworks are generally achieved through vertical lifting, if reinforced concrete brackets are arranged in the caisson grids, the conventional inner formworks of the prefabricated caisson structure cannot be normally installed and detached, and even the inner formworks can be locally improved, the installation and the detachment time can be greatly prolonged, and the prefabricated construction period of the caisson is seriously influenced. The conventional embedded steel member supporting structure is adopted, steel plates, screws and bolts are embedded in the outer wall of the caisson, and then the steel plates are combined and welded with the external steel plates to form a support. Therefore, from the viewpoints of convenience of construction, structural durability, and the like, it is necessary to optimize the caisson grid bracket design. Disclosure of utility model The utility model aims to provide an external bracket and a gravity type structure, which can greatly reduce the difficulty in installing and dismantling the inner template of a prefabricated caisson, save the construction period and avoid the problem of corrosion of reinforcing steel bars caused by contact with the reinforcing steel bars in the prefabricated caisson. The utility model is realized by the following technical scheme: the utility model provides an external bracket, includes vertical steel sheet, and two sides of vertical steel sheet are equipped with respectively perpendicularly and hang steel sheet and support the steel sheet, and the position that hangs the steel sheet is higher than the position of support steel sheet, hangs the steel sheet and forms the buckle after keeping away from the one end of vertical steel sheet and downwards vertical bending, hangs the steel sheet top and is equipped with a plurality of first reinforcing rib plates, and first reinforcing rib plate is connected with vertical steel sheet, and support steel sheet bottom is equipped with a plurality of second reinforcing rib plates, and the second reinforcing rib plate is connected with vertical steel sheet.
